Do big solar flares cause heat waves on Earth?
One big solar flare is not enough energy to cause heat waves on Earth, but if the Sun got more active, had many more solar flares and gave off more light, it could cause heat waves. In the early 1800s, there was a mini-Ice Age that appears to have been caused by a decrease in solar activity (the number of sunspots was smaller than usual for many years). But the Earth is large and doesn’t respond quickly to something like a single solar flare. Dr. Eric Christian • Violent Space Weather What if there was a solar flare or electro-magnetic pulse so violent that while biological life was mostly unaffected, communications satellites, power grids, and electronics of all kinds went out of service indefinitely? Can unusually strong solar activity physically damage electrical and electronic equipment significantly and permanently? Could equipment be shielded to prevent such interference? I don’t think that there is any way solar activity could destroy our electronics “permanently” without wiping
